I just bought a new Snyders 5.5 high compression head for a 28 aa. Motor is recently been rebuilt. Pulled the stock head to replace with the high compression one. When installing a high compression head is the torque the same or do I want to go higher? Also have the banana pop out cable on it. Does it need extra torque? What tricks do you recommend for installing the head? I have a 32 b head gasket for it
Thanks
 
Ask Snyders. They have a vested interest in making it work correctly. They also have a valid excuse to not stand behind their product if it wasn't installed according to their instructions.

Snyders recommends the composition head gasket. I have used many of them and it has the probability to fail . My preference is the BEST brand B head gasket for it. It use 55 lbs torque as a final torque in increments of 35,45,55.

I don't use a gasket on the water neck but surface it on my head resurfacer or belt sander and check for flat, use a good skim of RTV black and torque it like the others. Haven't ever had any issues doing that. If you use the Best brand composition gasket I use a coat of "copper coat on each side. The red silicone style is used as is.

Torque the head again shortly after 1st run and then a couple of times there after. I usually do 3 rounds and it should be good for a while.

Enjoy the head.. you will be glad you got it!

Ok I will give them a call. Engine overheated. And blew the head gasket. So I am trying to update it so I won't have trouble again
 
Many like the Best brand gasket @ 55 '#. The Best web site and sales/tech. rep. is very helpful if further info. needed.

Larry, those new head gaskets will work fine however I believe the issue is that most 'A/B' rebuilders do not have the proper equipment to be able to use them. It takes a Surfacer with a CBN (-or better yet, a PCD) cutter spinning at 1000+ RPM producing an RA finish in the mid-twenties. That allows the surface to be smooth enough where there is not any weeping.

I have the 6:1 head but I did not know enough to make an intelligent decision as to the differences between the 5.5:1. Are there pros or cons for each head? Anything that would be good to know for someone trying to decide which on to get.
 
Got the new head on last night and got it to run. This had to be the best thing o have ever boughten for it!!! It runs so much smoother and idles bettter. Can't wait to get the hood on and washed up and take the old truck for a ride! Thanks all
